Michelle Obama made a superstar entrance at the Grammy Awards on Sunday, taking the stage hand-in-hand with Lady Gaga, Jennifer Lopez, and Jada Pinkett Smith, before joining her friend and Grammys host Alicia Keys. Onstage, she gave a fiery speech about the power of music — in her personal life and outside of it — that threatened to steal headlines for the evening. But at least one person, Obama revealed, wasn’t particularly impressed by the former first lady’s starpower. On Wednesday, Obama shared images of a text exchange between her and her mother, Marian Robinson, captioning the conversation: “When your mom doesn’t think you’re a ‘real’ celebrity.”

“I guess you were a hit at the Grammys,” wrote Robinson.

“This text is so typically you … Did you watch it?!” replied Obama.

“I saw it because Gracie called me. Did you meet any of the real stars or did you run right after you were done,” replied Robinson, ruthlessly.

“I told you I was going to be on it…” responded the former first lady, adding: “I am a real star…by the way…”

Obama’s many achievements may leave her mother unphased, but the same could not be said for the crowd at the Grammys, who welcomed her on stage to thunderous applause. In her speech, Obama told the crowd that music had “always helped me tell my story,” and that she personally wanted to celebrate the way song “helps us share ourselves — our dignity and sorrows, our hopes and joys.” It reminded her, she said, to listen and appreciate the people around her, to hear “every story within every voice, every note within every song.”

In a picture from the night shared by the former first lady, Obama wrote that her decision to attend the Grammys was made in support of the event’s host, singer/songwriter Alicia Keys, a longtime friend who performed for the Obamas in the White House on multiple occasions.

“A big part of friendship is showing up for your girls — that’s why I was thrilled to be there for the one and only @aliciakeys at the #GRAMMYs,” wrote Obama. “She is one of the most genuine and thoughtful people I know — there’s no one better to help us all celebrate the unifying power of music!”

This is a disgrace. Where is the UK foreign office in all of this? Aras Amiri now joins another British-Iranian, Nazanin Zaghari-Ratcliffe, in notorious Evin prison on bogus charges. @foreignofficehttps://t.co/DJX0knhdot
